500 Series barrels fit the Ruger MK I, MK II, and 22/45 models.
Barrels are completely turned, threaded, chambered, crowned, polished,
and finished. They are made from Walther premium blanks, and are available
in chrome-moly or stainless steel. They are offered with or without
a replaceable, serrated-ramp, undercut, partridge, front sight. Barrel
lengths offered are 5-1/2" and 6-1/4". The 6-1/4" model
has a built in compensator. Installation requires lathe work.

(Part CLK-510) When used in conjunction with a trigger
job, this trigger allows for a sharper, crisper pull. It removes the
trigger sideplay that exists with a factory trigger. It can be fitted
to Mk I, Mk II, MkIII or 22/45 Ruger .22 semi-auto pistols. The trigger
features a micro-adjustable overtravel stop and a wide arc so the
trigger finger will not drag on the trigger guard. A sharp serrated
face with a wide, flat surface allows for finer finger pressure control.
Some fitting is required.

(Part 515) Oversized sear pin and hammer bushing provide
closer tolerances and allow for lighter, more consistent trigger job.
These parts are included with all Mk I and Mk II trigger jobs.

(Part 517) Not pictured ~ Oversized Hammer Bushing and Sear Pin that
we use on the Ruger 22/45 to obtain the best possible trigger job.
